BALING-PRESS.

SPECIFICATION forming part of Letters Patent N 0. 792,448, dated June 13, 1905. Application filed March 31, 1905. Serial No. 253,015.

To all whom, zit may concern:

. Be it known that I, JULIAN H. PITKIN, acitizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Baling-Presses, of which the following is a complete specification.

. This invention relates generally to means for presenting the material to be baled to the hopper, and is shown as being applied to a power-press of a well-known type.

The object in view is to produce a simple and effective mechanism for presenting the material to the feeder, to reduce the number of operative parts, and provide asimple means for alternately rendering inoperative the conveyer-chain and actuating the block-inserting device.

Other subordinate improvements will appear in the disclosure of this invention in the following description and in the accompanying drawings, in which- Figure 1 represents a side elevation of the principal parts of a baler in which is embodied my invention. Fig. 2 is a partial longitudinal section designed to show more particularly the connection between the feedlever and plunger and also the forward end of the feed-table and conveyer-chain mounted thereon. Fig. 3 is a transverse section taken through the feed-table and near the forward end thereof, as indicated by the line 3 3 in Fig. 1, the view illustrating the construction of the cam-track and the means for raising and lowering same. Fig. A is a fragmentary view showing in side elevation the forward end of the cam-track, the rear end of the bar for actuating the same, and adjacent cooperating parts. Fig. 5 represents an enlarged detail View showing in side elevation a portion of the cam-track with the conveyerchain in position thereon. Figs. 6 and 7 show in side and front elevation, respectively, one of the special links of the conveyer-chain. Fig. 8 is a plan view of the forward end of the feed-table, showing the convergently-arranged spring-held sides mounted thereon. Fig. 9 illustrates the manner of applying the plunger 3 operates.

springs to the pivotally-mounted side boards or walls. Fig. 10 is a transverse section taken immediately forward of the block-inserter,

as indicated by the line 10 on Fig. 1, and de signed to show the manner in which the blockinserter is operated by the bar, which extends rearwardly and controls the position of the cam-track beneath the conveyor-chain. Fig. 11 is a sectional view taken longitudinal of the feed-lever shaft, and Fig. 12 represents an elevation of the rear end of the baler.

Referring to the drawings, 1 designates the baling-chamber, the top and bottom sills 1 of which constitute the principal members of the frame of the baler.

2 is the compression-chamber, or that portion of the baling-chamber in which the usual Immediately above the compression-chamber 2 is the hopper 4, the sides of which are formed by the sheet-metal pieces 4: The plunger 3 is given a reciprocating movement through the pitman 3, which connects at its forward end with the large gear 5 on the shaft 5. The gear 5 is driven by the pinion 6 on the shaft 6, on which is also secured the large gear 6 which meshes with and is driven by the pinion 7 on the drivingshaft 7. On this driving-shaft 7 is also rigidly secured the fly-wheel 7 and the drive-pulley 7 (see Fig. 1,) about which passes the belt 7*, leading to a suitable source of power.

In suitable hearings in the standards 8, which rest upon and extend upwardly from a position near the forward end of the main frame, is the oscillating feed-lever 9, rigidly secured to the rock-shaft 9, on the free end of which is pivotedthe feeder-head 10, the said feederhead being controlled in its movement by the bar 11, interposed between the upper end of said head and the upper end of the standards 8. The feed-lever 9 is provided with a downwardly and forwardly projecting slotted arm 9, the slot thereof engaging a roller 3 on'the arm 3*, which rigidlyconnects with and extends upwardly from the plunger 3. In this manner an oscillatory movement is imparted to the feeder-arm from the reciprocating plunger.

The above parts are all confessedly old in principle, and as no claims to novelty are made thereto the foregoing brief general description will suflice.

A second roller 3 is also journaled on the arm 3" of the plunger, this roller engaging the longitudinal recess 12 in. the casting 12, and thus, in effect, constitutes an auxiliary guide for said plunger. This feature, however, will be covered by an application filed by me March 31, 1905, Serial No. 253,016.

Supported above the rear end of the balingchamber 1 on the outwardly-fiared portion 13 of the supports 13 is the bottom 14 of the conveyer-platform, the flared sides 14 thereof resting upon and being secured to the flared portions 13 of said supports. In the bottom of this conveyer-platform 14 are formed the two longitudinally-extendingslots 14 through which project the fingers 16 of the conveyerchains 15. Arranged below the conveyerplatform and near the front and rear ends thereof are the shafts 17 and 18, respectively, each shaft having secured to it at corresponding distances apart two sprocket-wheels, as 19, on which are mounted the conveyer-chains 15. To the forward shaft 17, at its outer end, is secured the driving sprocket-wheel 20, about which is made to pass the chain 21, the forward end of this chain engaging the sprocket-wheel 6 on the shaft 6, and in this manner imparting movement to the conveyer-chains 15. The shaft 17 journals in the standards 17, which rest upon and are secured to the top of the baling-chamber, (see Fig. 3,) while the standard 18 near the rear end of the conveyer-platform affords a suitable journal for the shaft 18. The upper run or ply of the chain 15 is made to extend immediately beneath the platform 14 of the conveyer in operative relation therewith, and to support the chain in this po' sition the guides 22, formed, preferably, of a Z-bar, are secured to the under side of the said platform, as clearly shown in Fig. 3. These Z-bars form channels in which the chain is securely held against lateral or downward movement. able intervals with the special links, having finger attachments, as shown in detail in Figs. 6 and 7. These fingers 16 have at their base comparatively short laterally-extendiug arms 16, on the ends of which journal the antifriction-rollers 16 It will be seen from an inspection of the several figures, but more particularly Figs. 1 and 3, that the fingers on the upper run of the chain are the onesin engagement with the hay, and to render them rigid in this position a cam-track 23 is provided. This cam-track is preferably formed of an angle-bar bent to a U shape, the limbs of the U forming a track on which the rollers 16 may run and the free ends of said bar being pivotally mounted beneath the rear end of the conveyer-chain and at the point 23, as shown in Fig. 1. It is evident that as the forward The chain 15 is provided at suitend of the cam-track 23 is lowered the rollers 16 on the arms 16 of the fingers will have no support, and in consequence will become flexible and drop rearward to an inoperative position, the degree to which the track is lowered determining the extent of the rearward drop of the said fingers. In Fig. 5 is shown in full lines theposition of the fingers 16 when the cam-track is in its raised or operative position and in dotted lines is shown the inoperative position of both the track and lingers, the track being dropped at its forward end about its pivotal support 23.

T o raise and lower the forward end of the cam-track 23, the following means are employed: To the forward end of the U-shaped angle-barforming the track a member 24, formed, preferably, of sheet metal having a U- shaped cross-section, is secured, (see Figs. '3 and 4,) the said member extending downwardly and presenting a flat surface to the engaging member below. In a suitable hearing, formed for convenience by the rearward extension 17 of the outside standard 17, is

journaled the bell-crank or rock-shaft 25, hav ing the arms 25 and 25 The inner arm 25 is arranged to engage the lower surface of the member 24 and in this manner when in an upright position will be made to bear the weight of the forward end of the cam-track 23. The downwardly-curved lip 24 on the member 24 limits the rearward movement of the arm 25 with respect to said cam-track, while to reduce friction both the arm 25 and 25 are provided with the rollers 26. reciprocating bar 27 pivotally connects at its forward end with the arm 28 on the rock-shaft 9 of the feed-lever 9, as shown in Figs. 1 and 11. To the rear end of this reciprocating bar 27 is secured the head-plate 29, in the lower side of which is formed the short verticallyextending slot 29, which receives the roller 26 on the outer arm 25 of the rock-shaft 25. It is evident that a reciprocating movement of the said bar 27 will when the roller on the arm 25 is engaged by the slot 29 impart a rocking movement to the shaft 25, and with it also the arm 25 thus advancing the latter arm to the dotted-line position indicated in Fig. 4, and thereby permit the forward end of the cam-track to drop. WVhen occupying the position shown by dotted lines in Fig. 4, the arm 25 will have disengaged the plate 24 on the forward end of the cam-track, andthe forwardly-extending strap 23 of said track will be made to rest upon the shaft 17.

WVhenever the feed-lever 9 descends, the reciprocating bar 27 will be caused to move forwardly, rocking the bell-crank formed by the shaft 25 and arms 25' and 25, which will, as before stated, drop the forward end of the cam-track 23 and render inoperative the conveyer-chain. Vhen the feed-lever 9 and.

feeder-head 10 return, the bar 27 will be moved rearwardly and the operation resion-block.

versed-that is, the conveyer-chain will be again thrown into action.

Such operation of the conveyer-chain, however,'cannot be continuous, as it must necessarily be interrupted to permit of the insertion of the usual divi- To properly interrupt its movement and to also actuate the division-block inserter, the following-described means are employed: A frame 30 is provided, in which the division-block is placed, the frame pivoting to the under side of the baling-chamber at the point 30. A foot-lever 31 is suitably mounted on the feed-table, pivoting at the point 31. From the free end of this lever depends a link 32, which loosely engages the bar 27, a roller 32' reducing the friction therebetween. Secured to the frame of the press forward of the block-holding frame 30 is the post 33, on the upper end of which pivots the lever 34. The upper end of this lever connects, by means of the link 34, with the frame 30 of the block-holder, as shown in Figs. 1 and 10. A depending arm 35 is secured to the bar 27 in such a position that its path of movement will be substantially equal forwardly and rearward of the lever 34, and on the lower end of this arm is formed the laterally-projecting tappet 35. The normal path of movement of the tappet 35 is below the end of the lever 34, as will be seen from an inspection of Fig. 10; but when the bar 27 is raised in its movement forwardly by the foot-lever 31 the said tappet will impinge the lever 34, swinging the top rearwardly, or to the right, as viewed in Fig. 1. This will swing the block-holding frame rearwardly with the block therein until a position is reached above the hopper, at which time the division-block will drop by gravity or be forced by the feeder-head 10 into place. That the tappet on the depending arm 35 may not press the lever 34 in the wrong direction the said arm is provided with a .knee or rule joint, as shown, and the spring 36 operates to return the frame 30 to its normal position.

Referring to Fig. 8, which represents a plan view of the forward end of the conveyer-platform, will be seen the two convergently-arranged spring-held walls 37,concave inwardly,

pivoted along their lower edges and held inwardly by the springs 38. These walls have their. pivotal axes at 38 and inclose the conveyer-chains 15. The hay will be forced forwardly by the fingers of the chains, compressed slightly, and directed into the hopper 4. In the event of an unusually large mass of hay gathering between the yielding walls 37 the springs 38 will permit the walls to spread and allow the hay to pass through. On one side of the platform 14 is arranged the feedtable 39, while on the opposite side thereof is the board 40, which with the rear end board 41 gives a hopper effect to the conveyer-platform.

The forward ends of the convergent walls 37 form a throat through which the material is fedin a continuous sheet or swath to the hopper 4, while the feeder-head 10, being of such a large base and transverse section, operates as a cut-off for such sheet or swath of hay. The rear side of the feeder-head is made of a considerable length in order to pre vent the hay lapping back over the top thereof and being withdrawn from the compressionchamber on the return of the feeder-head. The convergent or throat-forming ends of the walls 37 approach each other on their upper sides, and thus form a channel which is inclosed except a space above. The effect of this will be to restrain the swath or mass of hay in passing therethrough and enable the feeder-head 10 to break or interrupt said swath and force a comparatively clean charge free from the entangled and disengaged quantities of hay which usually connect the inserted charge with that in the throat of the conveyer. While the side of the feeder-head adjacent to the throat is the portion which cooperates with said throat to interrupt the flow or swath of hay, the other parts as well are made of considerable length to prevent the hay on all sides from engaging with and being withdrawn by the said feeder-head.

The operation briefly is as follows: Hay or other material operated upon is kept constantly upon the conveyer-platform, and assuming the parts to be in the full-line position of Fig. 1 the conveyer-chain is in operation, and the feeder-head begins to descend. The downward movement of the feed-lever 9 through the short arm 28 will move the bar 27 forwardly, or to the left, as seen in Fig. l, and concurrently with the feeder-head, 1O reaching the hay in the hopper the arms 25 and 25 will have-been rocked forwardly, as heretofore described, until the forward end of the cam-track 23 has dropped upon the shaft 17 permitting the fingers 16 to yield and rendering the chain inoperative. The feederhead continues its downward movement, forcing the hay from the hopper into the baling-chamber. The foregoing movement of the feeder has been produced by the return movement of the plunger and its connection with the feed-lever 9, already described. The plunger -now moves forward, and the feed-lever rapidly returns to its upper position, as is well understood, in doing which the bar 27 is made to move rearwardly, rocking the shaft 25 and arms thereon. This will raise the cam-track and again render operative the conveyer-chain.- The operation proceeds in this manner until it is desired to insert a division-block, at which time the reciprocating bar 27 is raised at the end of its forward movement by means of the foot-lever 31, the feed-lever 9 being in its down position, as shown by dotted lines in Fig. 1. This stops the feeding of the hay to the hopper, since in its raised position the said bar cannot engage and rock the shaft 25, and in consequence the cam-track 23 remains down. The feed-lever raises as usual, and in doing so causes the bar 27 to, move rearwardly; but because of the hinge in the arm 35 it is without efi'ect during its rearward movement. The feed-lever 9. now descends, drawing the bar 27 forward, and the tappet 35, will impinge the lower end of the lever 34, moving its upper end rearwardly, and before the feeder-head 10 will have reached the position shown in Fig. 2 the lever 34, acting through the link 3 L, will have moved the block-holding frame 30 to the right, or rearward over the compression-chamber 2, in which position the block will fall by gravity into position. The foot-lever 31 is now released, permitting the rear end of the bar, which is now in its forward position, to drop and engage the arm 25, raise the cam-track 23, render effective the conveyor-chain, and the operation continues in the same manner until it is desired to insert another block.
